有些用数学归纳法证明的命题,不仅与自然数n有关,而且还涉及其他可变因素,因此这类问题的“归纳”步骤往往较难完成。本文拟从构造辅助命题入手,来促进这类问题归纳步骤
Some propositions that are proved by mathematical induction are not only related to the natural number n, but also involve other variable factors. Therefore, the “induction” steps of such questions are often difficult to complete. This article intends to start by constructing propositional propositions to promote the generalization of these problems.
